MINE-CAE WHEEL.

To all whom it may concern:

Be it known that I, JAMES S. WooDcocK, a citizen of the United States, residing at New Lexington, in the county of Perry and State of Ohio, have invented certain new and useother closures for the oil inlet opening; to

provide improved means for retaining oil soaked packing in proper contact with the spindle, to provide improvements in the form of the oil chamber, the purpose of which will be hereinafter set forth and to produce other improvements the details of construction and arrangement of parts of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawing, in which:

Figure 1 is a view in elevation of one of my improved mine car wheels, Fig. 2 is a sectional view on line of Fig. 1, Fig. 3 is a sectional view on line y-y of Fig. l, and, Fig. 4 is a sectional view on line a-a of Fig. 2.

Similar numerals refer to similarl parts throughout the several views.

1 represents the wheel rim which may be of the usual flanged car wheel form, or of other suitable form for running upon a track rail. l

2 represents a central hub body or casing, the periphery of which is connected at intervals with the inner side of the wheel rim through the medium of tangential and curved spokes 3. rl`he hub member 2, as shown in the drawing, is in the nature of a casing which has its inner end slightly reduced in circumference and which is provided with a central tubular boxing orl bearing which is formed with said casing and extends therethrough as shown at 4.

Through the outer wall of the hub casing 2 is formed an oil opening 5. This oil opening 5 extends not only through the outer wall of the hub casing, but through a projection 6 on Speccation of Letters Patent.

ber 4 is formed near its inner end with oppositely located openings 7 and from the inner end of' the casing 2 and from the side walls thereof project lugs 8, these lugs being so arranged as to form about each of the bearing openings 7v openwork cages, each of which is adapted to contain packing or oil retaining and absorbent material. This packing is adapted to be placed in said cages by inserting the same, first, through the end of the spindle bearing opening, thence through the openings 7 into said cages.

As is shown more clearly in Fig. l of the drawing, that side of the casing in which is formed the oil opening 5 is provided with a lateral enlargement which is indicated at 2, the object of this enlargement being as will readily be understood, to provide substantially as great a depth or capacity for the oil containing chamber which is formed by the casing 2 below the oil opening 5 when the wheel is in the position indicated in Fig. 1 of the drawing, as exists between the periphery of the bearing member 4 and the wall of the casing 2 at other points. In this manner the rise of the volume of oil in the casing to a point where it will readily flow outward through the opening l5 when the wheel is in a position to bring the opening 5 beneath the spindle, is prevented.

In mine cars of this class where an oil receiving, containing and distributing chamber is formed within a central hub casing, various means have been employed for preventing the oil which is thrown against the end walls of the casing during the revolution of the wheel, from flowing or seeping out through the opening such as that indicated at 5, through which the oil is injected to the chamber.' The employment of valves and other similar closures for this purpose, have been deemed unsatisfactory not only for the reason that such valves are subjected to breakage, but that the use of the wheels on mine cars .necessarily requires their employment in coal dust laden atmosphere and a proper seating of the valves is often interfered with by coal dust working beneath the valve.

By the means herein described which consists of the internally projecting oil boss, the oil which is thrown about or comes into contact with the end walls of the casing, contacts with the inclined periphery of the projecting boss and is thus prevented from escaping through the opening 5.

It will also be observed that owing to the inclination of the outer surface or periphery of the boss, oil which contacts therewith will naturally be conducted to the end wall of the casing instead of toward the flaring larger end of said boss. It will thus be seen that the oil feed passage 5 may be left open without loss of oil.

Owing to the formation of the open cages produced by the clustering arrangement of the lugs 8, it will be understood that the packing contained in said cages will be held in position to absorb oil from-the interior of the casing and at the same time contact with the car axle spindle which is journaled in the tubular boxing 4.

What I claim, is:

l. A mine car wheel comprising a rim, a central journal bearing member having openings formed therein, an oil casing surrounding said bearing member, said casing having an oil feed opening therethrough adjacent said central bearing member, and said oil casing having an enlarged peripheral portion integral with and in direct communication with the remainder thereof, said oil-feed opening lying between said enlarged portion ing having an enlarged peripheral portion integral with and in direct communication with the remainder thereof, said oil feed opening lying between said enlarged portion of the casing and the journal bearing member, a pair of spaced transversely extending lugs lying upon each side of the oil opening in the journal bearing member, and lugs located at right angles to the first named lugs and infront of the Vspaces between said lugs, all of said lugs together forming a cage.

In testimony whereof I affix my signature in presence of two witnesses.
